NAME
neb-wipe
- Erase harddisk partitions in a very secure manner
SYNOPSIS
neb-wipe
[ -r
count
]
partition
DESCRIPTION
neb-wipe
uses the 35-pass overwrite method suggested by Peter Gutmann in
https://www.usenix.org/publications/library/proceedings/sec96/full_papers/gutmann/
OPTIONS
-
-r
-
Do not use the Gutmann method. Instead, overwrite the partition with
count
passes of random data.
-
-h
-
Show the usage.
EXAMPLES
neb-wipe -r7 sd0a
TODO
35 pass is not required for all encoding schemes. Maybe add a switch
to select overwrite patterns matching a desired scheme.
The used random numbers are generated by random(3), initialized with
an unsigned 32 bit seed read from /dev/urandom. Reading all numbers
from urandom is better since it contains entropy, but unfortunately this
is way too slow. Maybe add a compiled-in faster entropy random generator.
